I don't know the answer to the question, but I would have a similar problem in this situation. I have forms of identification, but none of the ones that MA say they will accept.
We don't have national ID cards in the UK, so that one is impossible.
I don't drive. Technically I can, and I do have a driver's license, but it's 20 years out of date because I haven't used it since 1998, with an incorrect address and in an old format (no photo) that isn't generally accepted as ID.
I don't have a valid passport because I haven't travelled outside of the UK since 2001. Passports expire after 10 years here, and the last time I had one I went for the full 10 years without using it once, so I haven't bothered renewing it. I could do it now but it would take a couple of months to sort it out (and cost me £75). Even if I did that, as Bonnie said above, our passports don't have an address on them, so it probably wouldn't be accepted by MA anyway.
If they don't accept the passport then the only way that a non-driver in the UK would be able to provide the (very specific) ID requested would be to learn to drive and successfully pass the test to get a valid license. If you were, for example, legally blind or partially sighted, or have cerebral palsy, even that would be impossible.
I have no idea what I would do if MA asked me to provide proof of my ID. Fortunately they never have.
You can say "I don't know the answer" or say "I think you're gonna have to get some" without being a massive dickhead about it.
